Architect’s and Engineer’s Specifications

The active subwoofer loudspeaker system shall incorporate one 15-inch low-frequency (LF) transducer mounted within a vented enclosure and tuned for optimum low-frequency response. System frequency response shall vary no more than ± 3 dB from 47 Hz to 120 Hz measured on axis. The loudspeaker shall incorporate a low-frequency amplifier system capable of delivering 500 watts RMS over a frequency range of 30Hz to 150Hz. The system shall provide 125 dB of continuous output and 128 dB of peak output. The amplifier system shall be mounted on an aluminum heat sink, which shall be mounted on the rear of the enclosure, and shall be convection cooled.

The rear-mounted amplifier assembly shall comprise separate signal and AC power panels separated by a large aluminum heat sink. The signal input panel shall contain two input and two loop-through XLR connectors, two high-pass output XLR connectors, a volume level control, a phase switch, and four status LEDs for Power ON, Signal Present, Limit, and Thermal functions. The system shall accept a stan-

dard line-level signal via the XLR input connectors. The power switch and IEC AC connector shall be located on the power panel.

Thermal protection shall be provided by a heat sink- mounted thermal sensor, which monitors the heat sink temperature and triggers the thermal protection circuit should the temperature exceed 140º F (60º C). The Thermal LED shall light and the input signal shall be muted until the heat sink cools to a safe operating temperature, at which point the thermal protection circuit auto-resets and normal operation resumes.

Overload protection shall be provided by a limiter circuit, which monitors the amplifier output and reduces the input level to the amplifier should the amplifier output begin to clip.

The enclosure shall have a rectangular shape and shall incorporate two side handles, one on each side, and a top-mounted pole receptacle. The enclosure shall be constructed of multi-ply wood.

The active subwoofer loudspeaker system shall be the Mackie Designs SWA1501.
